That's exactly what they did for the first DVD releases in the mid-2000s. Made it a bit jarring for some of the iconic scenes.

I believe the Shout Factory releases a few years back restored the majority of it though.

OK, you made me look at that channel again. I thought WKRP was on at 5:30 (remember the days when you could only watch a show when it was "on"?) but it turns out it was 9:30 today.

I only heard a few seconds of Another One Bites the Dust and I'm not sure if it was the Queen version or not.

The closing music was custom, I think. So maybe they are just using the non-problematic episodes.

So fun to visit the backwaters of the TV world. They had a commercial for a product that helps you GAIN weight!
